1 COUNTER-STIFFENER MACH|NE.I

SPECIFICATION forming part of Letters Patent No. 377,468, datedApplication filed August 15, 1887. Serial No. 246,927. (lo model.)

To all whom it may concern:

Be it known that I, LEWIS lB. RUSSELL, of Lynn, county of Essex,-Stateof Massachusetts, have invented certain new and useful Improvements inCounter- Stiffening Machines, of which the following` is aspeciiication, reference being had to the drawings accompanying andforming a part hereof, in

Figure l is a horizontal sectional View, 'and Fig. 2 isla verticalsectional view, of a common form of mold such as is in use in machinesfor shaping boot or shoe counters, showingl my improvement attached.

In the drawings I haveshown onl y the outer or female mold, since theother parts of the machine are familiar to those skilled in the f art;and reference to them is not necessary in describing my presentimprovement. I

It will also be understood that I have shown in the drawings but oneform of mold, although my improvement is applicable to any of the formsof mold known to me, and its application to any of these forms willbe'obvious.

The female molds of counter-shaping Inachines which actv on the exteriorof the counter are usually constructed in two or more parts, and areknown'to the trade as divided molds. They are thus divided because theform.to which thecounter is molded, and on which the counter-blank isplaced to be acted upon by the divided mold, is of a heel shape,

and being narrower at the shank part of the heel thanlmidway of theheel,the female mold must open to receivethe heel-shaped form, andVafter it has been closed upon it to mold the counter thereon it must beopened again to allow the heel-shaped form to be withdrawn. Thisdividing of the mold causes a seam or 4o joint where the parts of themold come to- .getheig and when the mold.acts upon the counter a creaseor mark appears thereon at the point where the joint in the mold occurs.These creases or ridges are objectionable, Since the whole exterior ofthe counter should be smooth in order 'to produce the best results. Thedivided molds'are usually made ofiron,and

after usefor a time on such material as leather or leather-board, ofwhich counters are made, they become worn irregularly, their interiorshape becomes modied to a greater or less for in any other convenientmanner.

surface of the counter. for its object the remedying of these defects,

as also the `attainment Ol" certain other. advantages, which will behereinafter referred HE RUSSELL to;l and it-consists in the applicationto the female mold of a lining or interior layer of material havinggreater or less iiexibility.d

My improvement and the Inode I have used of applying it will be readilyunderstood from the following description, to which reference is made inthe accompanying drawings.

The parts marked A B C are respectively Y the back and sides of athree-partl divided mold, the sides B and G being hinged, as

shown at k, Fig. 1, to the back'piece, A.

D is the lining,of somewhatyielding flexible i material, which I Secureby screw-boltsf to the sides ofthe mold.l y

The precise method of securing the lining in position is not importantsolong as its interior surface is smooth. The layer D of yielding and n'flexible material is continuous, and I'prefer for the purpose rawhide orleatheroid, since these materials may be conveniently given the means ofthe exact shape required, and are very tough and hard, keeping theirshape well and wearing y withgreat smoothness and uniformity. rlheylayer D may be easily tted to the shape of the mold or to theexactshape of the counter Y n required for a given style orclassof goodsby wetting a piece of the materiahand while it is moist and pliabletting it closely onto the form or last and drying itin that position;yor it maybe rolledinto shape when dry or molded by means of vmolds oflthe ordinaryk construction. After being given the required shape;

it is applied to the interior of the mold and' I secured by the bolts f,as heretoforev described, When.

the hinges or pivots k may be dispensed with,

the iiexible lining forming a sufficienthinge. n y f 95 the contour ofthe counter produced, this may When it is desired to very slightlymodify roo . myself to a lining consisting of a continuous layer in thesense of a layer that is integral throughout; nor do I wish to limitmyself to the application of my improvement to what are usually calleddivided molds, as it may be successfully employed in sectional ordoubleprocess molds, such as are shown in Letters Patent No. 292,514,granted to N. J. Simonds, dated January 29, 1884. In molds of the kindlast named the superior surface finish which the counters receive fromcontact with the rawhide lining `will be very apparent.

I am aware that molds for counter-machines have heretofore been linedwith metal, and I therefore disclaim metal as a lining for such molds.It has, however, been found in practice that a lining of yielding andfiexible ma terial-such as rawhide or leatheroid-givesa better finish tothe counters than can be secured by a lining of metal, as it yieldssomewhat to compensate for the unequal thickness of the stock to becompressed in forming the counters, and its elasticity orcompressibility also contributes to an improved finish of the counters.The rawhide or leatheroid is also more easily molded or fitted intoproper shape for the mold-lining than metal.

What I claimisn A divided or sectional mold for countermachines having asmooth and continuous interior layer or lining of rawhide or leatheroidattached to the mold and closely fitting against and covering 'theentire interior thereof, substantiall y as set forth.
